This patch addresses a kernel bugzilla report and two recent mail threads.
The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632,
which reports a udev timeout on boot.
The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/
linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a
suspend/resume cycle for rtl8192cu.
The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2)
concerned changes in udev that break drivers that delay while firmware is loaded
on modprobe.
This patch converts all rtlwifi-based drivers to use the asynchronous firmware
loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common
callback routine. Driver rtl8192se needs different handling of the firmware,
thus it has its own code.

Fix multiple bugs in event tracing:
1) If you enable uCode tracing with the device down,
it will still attempt to access the device and
continuously log "MAC is in deep sleep!" errors.
Fix this by only starting logging when the device
is actually alive.
2) Now you can set the flag when the device is down,
but logging doesn't happen when you bring it up.
To fix that, start logging when the device comes
alive. This means we don't log before -- we could
do that but I don't need it right now.
3) For some reason we read the error instead of the
event log -- use the right pointer.
4) Optimise SRAM reading of event log header.
5) Fix reading write pointer == capacity, which can
happen due to racy SRAM access
6) Most importantly: fix an error where we would try
to read WAY too many events (like 2^32-300) when
we read the wrap counter before it is updated by
the uCode -- this does happen in practice and will
cause the driver to hang the machine.
7) Finally, change the timer to 10ms instead of 100ms
as 100ms is too slow to capture all data with a
normal event log and with 100ms the log will wrap
multiple times before we have a chance to read it.

For every WMI_SET_HOST_SLEEP_MODE_CMDID command (send from the host),
the firmware sends WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID as
an acknowledgement to the host.
In order to being sync with the firmware, the host has to wait for
WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENT event before going to
the suspend state. This patch ensures ath6kl_wow_suspend() waits
until it gets this event after sending set host sleep mode command.
This patch adds,
* New command WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID in
WMI event table.
* New WMI function ath6kl_wmi_host_sleep_mode_cmd_prcd_evt_rx()
to process the event.

First preference is given to the user configured WOW patterns.
If the user doesn't configure any patterns (for ex, via iw command),
the default patterns will be configured based on the current mode
(vif->nw_type) while going to WOW suspend.
Summary of changes:
* ath6kl_wow_ap() is added to configure the below default
patterns when the system enters into WOW suspend in AP mode.
+ Unicast IP, EAPOL-like and ARP packet pattern
+ ARP packet pattern
+ mDNS/SSDP/LLMNR pattern
+ DHCP broadcast pattern
* ath6kl_wow_sta() is added to configure the below default
patterns when the system enters into WOW suspend in STA mode.
+ Unicast packet pattern
+ mDNS/SSDP/LLMNR pattern
* Move the user provided WOW patterns configuration code
from ath6kl_wow_suspend() to a separate function called
ath6kl_wow_usr().
* Two argument variable's ('filter' and 'mask) data type in
ath6kl_wmi_add_wow_pattern_cmd() are changed from 'u8 *' to
'const u8 *'. This is needed to make all pattern and mask
arrays to be 'static const u8' in the caller function.
* New conditional check is added to make sure user
configured pattern count is within the limit (WOW_MAX_FILTERS_PER_LIST).

Using this patch, the user can bypass existing auto
suspend mode selection logic and force ath6kl to enter
into the suspend mode what he/she wants.
If the user doesn't choose any suspend mode while doing
insmod of the driver, auto suspend mode selection logic
will kick in and choose suspend mode based on the host
SDIO controller capability.
Generic module parameter is required to specify suspend
mode including Deep Sleep and WOW while doing insmod.
Renaming existing mod param variable suspend_cutpower
would be sufficient to meet this requirement.
New module parameter suspend_mode can take any one of
the below suspend state,
1. cut power
2. deep sleep
3. wow

When an interrupt comes in, we read the reason
bits and collect them into "trans_pcie->inta".
This happens with the spinlock held. However,
there's a bug resetting this variable -- that
happens after the spinlock has been released.
This means that it is possible for interrupts
to be missed if the reset happens after some
other interrupt reasons were already added to
the variable.
I found this by code inspection, looking for a
reason that we sometimes see random commands
time out. It seems possible that this causes
such behaviour, but I can't say for sure right
now since it happens extremely infrequently on
my test systems.

In the early days, this was a quite useful software
feature for testing different regdomains and chain
configurations without adding debugfs cruft into
the driver. Nowadays, the driver's phy code seems
to be stable and there's no need for it anymore.
Therefore I decided to removed altogether.

Currently mwifiex_private pointers are derived from wiphy
structures. This will always work as long as there is only
one net_device associated with one wiphy. In scenarios where
there are multiple net_devices associated with single
wiphy, one should use net_device to derive the priv.

Current implementation, for retrieving priv from adapter,
uses bss_index. In multi interface environment supporting

Use bss_type along with bss_num to retrieve the priv.
